Wiring diagram for single light switch

When looking for a wiring diagram for a light switch, you first need to ask yourself what kind of a light switch you are working with. In most home wiring situations, you will likely only find three types of light switches. The most common light switch is the single pole light switch. The 1-pole light switch will have two terminals on it, and possibly a third terminal that is a ground connection. If you only have one cable in the device box, then the switch outlet is likely wired as a switch leg drop. You should only have two wires connected to the main switch terminals; one being a white wire identified by black tape or marked with a black felt pen to one terminal, and one black wire connected to the other terminal. The bare ground wire should be connected to the grounding terminal if there is one present. The device or outlet box must be connected to the ground wire if it is a metal box and to a plastic device box if there is a ground screw and grounding strap as an integral part of the box. If there are two or more cables in the outlet box, the main switch terminals will likely have a black wire on each terminal, or possibly a black wire on one and a red wire on the other terminal. Here is a wiring diagram for a switch single pole. Another type of switch you will encounter within the home is a three way switch.

Single-pole wall switches are used in circuit configurations where a light or group of lights is controlled from a single wall location. Single-pole switches can also control appliances or electronics. For example, a single-pole switch may be used to control power to an outlet that powers a floor lamp, stereo, or video system. Single-pole switches are by far the most common type of switch in a home, and because they get lots of use, sooner or later it's likely one will fail. Replacing a standard single-pole switch is among the easiest of all wiring problems to fix. But all electrical repairs come with some risk of shock, so it's important to have some basic understanding of wiring circuits in order to perform this repair. A wall switch is a device that controls the flow of current through the live "hot" wire of an electrical circuit. When in the open OFF position, the switch stops the flow of current from the source to the light fixture or other device. When switched to the closed ON position, the switch restores the flow of current through the entire circuit, allowing the light fixture to illuminate or the appliance to run. Thus, a wall switch is always connected to hot circuit wires, and it usually does not have a neutral connection at all.

When the electrical source originates at a light fixture and is controlled from a remote location, a switch loop is used. This circuit is wired with a 2-wire cable running from the light to the switch location. The neutral from the source is connected directly to the neutral terminal on the light and the source hot is spliced with the white loop wire. The white wire is marked black on both ends to identify it as hot. At SW1 it is connected to one of the terminals.
